| Resumo: | The population growth and the development of the pharmaceutical industry, there is a significant increase in the demand for drugs. In the last decade, studies have pointed to the occurrence, in water bodies, of emerging contaminants such as organic micropollutants, which include drugs. These are recalcitrant to conventional effluent treatment process due to their derived active principles; their toxic content can change the balance of the aquatic ecosystem. The advanced oxidation process is an alternative chemical process for the treatment of contaminated water by organic micropollutants, among the techniques of this tool there is the photo-Fenton that uses the reaction of Fe2+ with H2O2 (hydrogen peroxide) in the presence of light UV-visible, which promotes the formation of hydroxyl radicals, highly oxidant, which acts in the degradation of the contaminant. Thus, this study aims to analyze, through the absorbance obtained with a UV-visible spectrophotometer, the degradation of the drug Acetaminophen (N-4-hydroxyphenyl-ethanamide), Paracetamol, in aqueous medium using the photochemical process of photo-Fenton. After 60 minutes of reaction, among the 6 experiments, the experiment 3 showed the best result with 98.32% removal of paracetamol whose concentrations were 0.494 mM of iron and 739.7 mM of hydrogen peroxide. Thus, the photo-Fenton process was efficient as an alternative for the degradation of paracetamol, and it is shown to be a promising technique for the treatment of water contaminated by emerging organic micropollutants. |
